j Be it lm'own' that 1, CHARLES, Rnnntriis, a

ark, in the county of Jersey,

citizen'ofthe United States; residing at New-- Essex and State of Bewfication.

This invention relates to a fuse box or protective device for apparatusemployedin electric cn'cuits and relates P1Tt101llflTly iO that class offuse'boxes which are positive in act-1on,-that is, in wluch the fusedevice can.-

not attain and remain in a; molten hangingcondition before beingruptured an excess current.

.In carryin out my invention, I preferably employ a casing, terminalconnections-therein, afuse device, means electrically connected .to thesaid terminal connections and'nornially heldiir an operative position bythe saidfuse device and means operative upon the passage of an excesscurrent for throwing the aforesai'l means mto an inoperative positionand thereby opening the circuit, as will behereinafter more particularlydescribed.

In the drawing, Figure my improved fuse box, showing the same with thecover open. Fig. 2 is an elevation of the fuse box with. the coverclosed. Fig. 3

is a section on line so, 12:, Fig. '2, and' Fig. 4 is a section on line1 y, Fig. 2. I

Referring .to the drawing- (t designates a casing which is preferablymade rectangular in cross section and. of asbestos, vulcabeston or another suitable insulating material or compounds of'insulating materials.The casing a on one side thereof is provided with a cover I) which isshown as connected to the casing by .means, of the hinges 10. This coverI) may be provided with a knob 1 1', and the top of the casing with thespring catch 12, by means of which the; door or cover is normallysecured in position.

Within the casing (1 1T. employ a partition c made of fiber or any otherinsulating material and extending from the'hottom of the casing to apoint appreciably distant from the top member thereof. This partition 0substantially divides the interior of the casing into two equalcompartments and in .each ofthese compartments and in similar positionstherein, I employ a binding post or terminal C-OllllGC-tiOll'IZ which isadapted to re l have invented a-n- Improvement in 71* use-Boxes,ofpwluc-lrt-lre following is aspec l with theterminal (Z- 1 excesscurrent 1 enmg of the fuse wire, the swing or uEWAmgnn JERSE ,asseuorrrocenutmm Y MALLEABLE' IRON ooMPA 1 \r,..Q ti
